Doosan crawler excavators have an electronic power optimizing system (EPOS), which provides multiple power modes to help you adapt to your work. Choose from:
Many models optionally feature two intelligent boom float modes to help operators focus on their task while increasing the machine's efficiency.
• In float mode, the boom is allowed to move up and down freely, without hydraulic flow, making it ideal for finishing work and truck loading
• In breaker mode, the boom freely moves downward, reducing machine and attachment wear while improving operator comfort.
This optional feature is beneficial for straight forward and backward travel, which is ideal in trenching applications. A single foot pedal controls both tracks.
Each Doosan crawler excavator is designed for long life with a sturdy frame and reinforced upper structure.
Pin points on the boom and arm are cast for extra strength in tough working conditions. Additional reinforcement around the bosses and internal gussets ensure long life for your workgroup, even in tough applications.
The bucket pivot pin features a polymer shim to reduce wear and increase grease retention, while bushings and ultra hard wear disks are designed for extended service intervals and steady performance.
Doosan Connect Telematics provides machine intelligence from a device that comes standard on most Doosan machines. The device communicates wirelessly through cellular or satellite communication, making a wide range of machine information available to owners, dealers, and Doosan. Machine information can be viewed via the CoreTMS website from a computer or smartphone. Available information includes fleet status, machine location, operating hours, fuel usage, engine idle vs work time, error codes, engine/hydraulic oil temperature and various other data points. A three-year subscription is standard on all excavator models.
Cooling systems on Doosan excavators have more cooling capacity. On select models, a variable speed hydraulic cooling fan regulates airflow through the oil cooler. The increased cooling capacity allows the engine to run more efficiently at the optimal operating temperature range.
Select machines feature separate engine and oil cooling systems, each with its own cooling fan. On models equipped with a variable speed hydraulic cooling fan, the cooling system is allowed to operate at its optimum temperature to increase efficiency and extend the life of components.
A durable x-chassis, strengthened boom and arm assembly, and extended greasing intervals reduce maintenance costs and extend machine life. Easily access the battery, oil filter, air cleaner, fuel filter, radiators and other engine components.
The greasing system simplifies boom and arm daily maintenance. From centralized locations that are accessible from ground level, you can quickly grease multiple areas of the arm and boom.
Other features include boom pivot bushings with greasing intervals of 250 hours, bucket pins with greasing intervals of 50 hours, a block heater, and an automatic belt tensioner.
Doosan crawler excavators bring more comfort to your work with world-class cabins that combine superior comfort, excellent visibility, low noise levels and a roomy environment.
The pressurized cab keeps the operator environment clean and comfortable, while sound suppression keeps machine noise low to reduce operator fatigue. A new cabin mount reduces cab vibration by 20 percent and noise levels by 1.8 dBa. A new door window position delivers improved visibility.
A reclining, height and weight-adjustable air suspension seat offers better lumbar support and includes a headrest and adjustable armrest. An emergency engine stop is located at the base of the seat.
Work naturally with controls that are right where you need them. Easy-to-operate joystick controls make precise machine movements easy, while additional buttons are available for control of equipment such as hydraulic clamps. The high-performance air conditioning offers adjustable airflow and five operating modes.
Your machine keeps you in the know with an easy-to-read, multi-function display panel. It informs operators of the engine coolant temperature, fuel & DEF level and hydraulic oil temperature. It also includes the digital engine RPM and 15 different machine warnings. Monitor your fuel usage with gauges that display both levels and consumption.
All models include a standard rear view camera that can display machine information and video simultaneously. A side view camera is optional. Choose between three display modes:
• Rear camera
• Side camera
• Split screen (rear and side camera)
